ACADEMIC READING PRACTICE TEST 5
Reading Passage 1
You should spend about 20 minutes on 
Questions 1 - 13
, which are based on 
Reading Passage 1 below.
Sleep
Historically, it was difficult to study sleep. Not much can be gleaned from observing 
recumbent persons and questionnaires are no use, because people remember little of their 
experience during sleep. The breakthrough came in the 1950’s with electroencephalogram 
(EEG) recordings of brain electrical activity, when it was confirmed that sleep is anything but 
dormant.
We need sleep for biological restoration. It promotes cell growth, regeneration and memory 
consolidation. By shutting down most of the body’s machinery, resources can be focused on 
repairing damage and development. When people are deprived of sleep for any reason, there 
is deterioration in performance, particularly on tasks requiring concentration, and eventually, 
behaviour becomes shambolic. The individual becomes progressively incoherent and irritable 
and, after a few days, may experience delusions and hallucinations. The disruptive effects of 
sleep deprivation have even been successfully used as a basis of persuasion in interrogation.
A vital part of sleep is dreaming, which happens most intensively during rapid eye movement 
(REM) sleep. We typically spend more than two hours each night dreaming, though this 
is often spread over four or five separate periods. Infants spend up to 50 per cent of their 
sleep time in REM sleep, which is understandable when one realises that REM sleep is the 
time used for brain development, as well as learning, thinking, and organising information. If 
people are woken when REM sleep commences, depriving them specifically of dream-sleep, 
the proportion of REM sleep increases once they fall asleep again to make up what was lost. 
This suggests that REM sleep is an essential aspect of sleep.
Sleep and sleep-related problems play a role in a large number of human disorders and 
affect almost every field of medicine. For example, problems like a stroke tend to occur more 
frequently during the night and early morning, due to changes in hormones, heart rate, and 
other characteristics associated with sleep. Sleep also affects some kinds of epilepsy in 
complex ways. REM sleep seems to help prevent seizures that begin in one part of the brain 
from spreading to other brain regions, while deep sleep may promote the spread of these 
seizures. Sleep deprivation can also trigger seizures in people with some types of epilepsy.
The neurons that control sleep interact strongly with the immune system. As anyone who 
has had the flu knows, infectious diseases tend to make people feel sleepy. This probably 
happens because cytokines, chemicals produced while fighting an infection, are powerful 
sleep-inducing substances. Sleep helps the body conserve energy that the body’s immune 
system needs to mount an attack.
Sleeping problems occur in almost all people with mental disorders, including those with 
depression and schizophrenia. People with depression, for example, often awaken in the 
early hours of the morning and find themselves unable to get back to sleep. The amount 
of sleep a person gets also strongly influences the symptoms of mental disorders. Sleep 
deprivation is an effective therapy for people with certain types of depression, while it can
